E) pyramidal cells of field CA4.

The entorhinal cortex is the primary input to the hippocampus, providing both sensory information from various cortical areas and feedback from the hippocampus itself. The granule cells of the dentate gyrus receive inputs from the entorhinal cortex via the perforant pathway, but they are not the primary input. The nucleus accumbens is not directly connected to the hippocampus. Field CA2 is a small subfield of the hippocampus and is unlikely to provide primary input. There is no CA4 subfield, so pyramidal cells of field CA4 is not a correct choice.
